Supplemental material: The architecture of oceanic plateaus revealed by the volcanic stratigraphy of the accreted Wrangellia oceanic plateau

Geosphere, February 2010, v. 6, p. 47-73, doi:10.1130/GES00212.1, Supplemental Data File 4 - ⁴⁰Ar/³⁹Ar analytical data. This Microsoft Excel file contains the analytical data for the ⁴⁰Ar/³⁹Ar dating method for the 20 mineral separates analyzed at the Noble Gas Laboratory in the Pacific Centre for Isotopic and Geochemical Research at University of British Columbia. Age spectra and isochron diagrams for each of the samples are shown along with all the analytical data from incremental step-heating. The analytical methods are summarized in the Supplemental Methods File. Where multiple analyses of a single sample were made, all the results for each sample are included in a single worksheet in this workbook.
